Abstract
An opaque image-recording element for an ink-jet printer which comprises an opaque substrate having on at least one surface thereof a lower layer of a solvent-absorbing microporous material which comprises: PA1 (a) a matrix of substantially water-insoluble thermoplastic organic polymer; PA1 (b) finely divided substantially water-insoluble filler particles, of which at least 50 percent by weight are siliceous particles, the filler particles being distributed throughout the matrix and constituting from 40 to 90 percent by weight of the microporous material; PA1 (c) a network of interconnecting pores communicating substantially throughout the microporous material, the pores constituting from 35 to 95 percent by volume of the microporous material, and an upper image-forming layer of porous, pseudo-boehmite having an average pore radius of from 10 to 80 .ANG..
